In this paper an energy equivalence approach is suggested for the dynamic analysis of tapered chimneys. For any mode of vibration; by equating the kinetic energy of the actual chimney 1o that of an equivalent prismatic chimney, a hypothetical equivalent uniform mass has been obtained for the equivalent chimney. Also, by equating the strain energy of the actual and equivalent prismatic chimney, a hypothetical equivalent constant moment of inertia has been derived for the equivalent chimney .The accuracy of the proposed equivalent prismatic model has been checked by comparing the results with that of the conventional segmented model using the stiffness method, which is deemed to be the more rigorous solution. Free and forced dynamic analys

This letter to the editor provides commentary on a previously published case and highlights additional diagnostic and genetic considerations in cystinosis.

This paper presents a comparative study between different oil production enhancement scenarios in the Saadi tight oil reservoir located in the Halfaya Iraqi oil field. The reservoir exhibits poor petrophysical characteristics, including medium pore size, low permeability (reaching zero in some areas), and high porosity of up to 25%. Previous stimulation techniques such as acid fracturing and matrix acidizing have yielded low oil production in this reservoir. Therefore, the feasibility of hydraulic fracturing stimulation and/or horizontal well drilling scenarios was assessed to increase the production rate. While horizontal drilling and hydraulic fracturing can improve well performance, they come with high costs, often accounting for up t

Urban growth of cities is connected with three related problems, the first one, is the deterioration of the center, which is a mark for historical origin. The second is the emergence of city edge, which contradicts by the center. The third one is the rapid semi urbanism of the edge. Literature review showed that Baghdad historical center (Old Rusafa and Karkh) had grown in four morphological stages, during which main paths had been changed from those which were perpendicular to the river front to those parallel to it. Research problem is that “there is a knowledge gap about the direction and origin of paths within Baghdad old center, after its growth”. The first research hypothesis is, “the direction of paths within old Baghdad cen

The prediction of the blood flow through an axisymmetric arterial stenosis is one of the most important aspects to be considered during the Atherosclrosis. Since the blood is specified as a non-Newtonian flow, therefore the effect of fluid types and effect of rheological properties of non-Newtonian fluid on the degree of stenosis have been studied. The motion equations are written in vorticity-stream function formulation and solved numerically. A comparison is made between a Newtonian and non-Newtonian fluid for blood flow at different velocities, viscosity and Reynolds number were solved also. It is found that the properties of blood must be at a certain range to preventing atheroscirasis

Excessive skewness which occurs sometimes in the data is represented as an obstacle against normal distribution. So, recent studies have witnessed activity in studying the skew-normal distribution (SND) that matches the skewness data which is regarded as a special case of the normal distribution with additional skewness parameter (α), which gives more flexibility to the normal distribution. When estimating the parameters of (SND), we face the problem of the non-linear equation and by using the method of Maximum Likelihood estimation (ML) their solutions will be inaccurate and unreliable. To solve this problem, two methods can be used that are: the genetic algorithm (GA) and the iterative reweighting algorithm (IR) based on the M

Sultan Said bin Sultan bin Ahmed bin Said Al-Busaidi (1223-1273 AH / 1806-1856 AD) was able to rule Oman and Zanzibar in a unified Arab-African state during his reign. However, it was separated for several reasons. Thus, the study aims to clarify the efforts made by Sultan Said for annexing Zanzibar to Oman, establishing the Arab-African Sultanate, and shedding light on the role played by Britain in dividing the Arab-African Sultanate and separating Zanzibar from the Omani rule in (1275 AH-1861 AD). The study has adopted the historical descriptive analytical approach. The study has reached several conclusions, such as: The economic motivators  were the most important factors that pushed Sultan Said to move his capital from Muscat to

Eine in fast allen Kommentaren zu der Satzbaubeschreibung gegen die arabischen Nationalgrammatiker gerichtete Kritik ist, daß sie den Satzbau des Arabischen nicht unter einem Hauptgesichtpunkt gefaßt und zusammenhängend entwickelt, sondern mehr in einzelne Teile auseinander gelegt haben, in der Weise, daß sie vom Einzelnen zum Ganzen ausgingen. Solch eine reversible Vorgehensweise gilt nach Ansicht vieler Arabisten als der Hauptmangel der arabischen Traditionsgrammatik.[1]

Ich nehme darüber hinaus an, daß die frühen arabischen Traditionsgrammatiker die Grundwortstellung sogar nur am Rande diskutiert haben, daß es sich in ihren grammatischen Abhandlungen kein Sonderkapite
